Stator for rotating electric machine

Abstract

A stator is applicable to a rotary electric machine that includes a terminal block. The stator has a stator coil. The stator includes a lead wire drawn out from the stator coil, a bus bar, a first terminal electrically connecting the lead wire with the bus bar, and a second terminal electrically connected to the bus bar and fixed to the terminal block. The first terminal includes a first thermal bonding bonded to the lead wire by thermal caulking or welding, and a first mechanical coupling mechanically coupled to the lead wire at a position closer to the stator coil than the first thermal bonding.

What is claimed is: 
     
         1 . A stator applicable to a rotary electric machine including a terminal block, the stator comprising:
 a stator coil;   a lead wire drawn out from the stator coil;   a bus bar;   a first terminal electrically connecting the lead wire with the bus bar; and   a second terminal electrically connected to the bus bar and to be fixed to the terminal block, wherein   the first terminal includes
 a first thermal bonding bonded to the lead wire by thermal caulking or welding, and 
 a first mechanical coupling mechanically coupled to the lead wire at a position closer to the stator coil than the first thermal bonding. 
   
     
     
         2 . The stator for the rotary electric machine according to  claim 1 , wherein
 the lead wire includes
 a covered part in which a conductor is covered with an insulating film, and 
 an exposed part in which the conductor is exposed, 
   the first thermal bonding is bonded to the exposed part, and   the first mechanical coupling is coupled to the covered part.   
     
     
         3 . The stator for the rotary electric machine according to  claim 1 , wherein
 the second terminal includes
 a second thermal bonding bonded to the bus bar by thermal caulking or welding, and 
 a second mechanical coupling mechanically coupled to the bus bar at a position closer to the first terminal than the second thermal bonding. 
   
     
     
         4 . The stator for the rotary electric machine according to  claim 1 , wherein
 the first terminal is formed in a plate shape and has a first surface and a second surface, which is opposite to the first surface,   on the first surface, the first thermal bonding is bonded to the lead wire,   on the first surface, the first mechanical coupling is coupled to the lead wire, and   the bus bar is fixed to the second surface.   
     
     
         5 . The stator for the rotary electric machine according to  claim 1 , wherein
 the lead wire extends from the stator coil in a direction toward the second terminal, and   the bus bar extends from a connection part with the first terminal in a direction toward the second terminal.
